D-30Bypass Turbofan Engine with Cooled Blades of the Turbine 1st Stage

The parameters of bypass turbofan engine D-30 were as good as the parameters of the best foreign engines of that class, and many of the parameters superseded them. Developed within an amazingly short period of time (about three years), the engine turned to be the most reliable one in the history of the domestic engine building. The D-30 development was recognized with the USSR State Prize.

Bypass turbofan gas turbine engine D-30 for short-haul passenger aircraft Tu-134 was created in 1964. In 1966, the engine was put into serial production.

Engine D-30 has a two-stage compressor, a can-annular combustion chamber, a 4-stage turbine. D-30 was the first engine in the domestic engine-building industry to use cooled blades of the turbine 1st stage made of the newest heatproof material of the time and an exhaust nozzle with a lobe mixer. The technical and efficiency parameters of D-30 were similar to those of the best world’s engines of that class.

In 1969, the D-30 engine of the second series was created having a thrust reverser and an improved control system. The engine was produced in 1970 through 1987 and was used on the Tu-134FA, Tu-134B, Tu-134AK aircraft.

In 1980, the D-30 engine of the third series was created with the maximum thrust of 6930 kgf (with preserving it at up to до = +C). The number of the engine compressor stages was increased to 5, the gas dynamic stability margin was improved, the system was introduced that protected against over-thrust and gas over-temperature. The D-30 engine of the third series was produced in 1983-1993. These engines are installed on passenger airliners Tu-134-A-3, Tu-134B-3, Tu-134UB-L. It shall be noted that the core of the third-series D-30 was taken as a base point for developing gas turbine plants for the Russian fuel and energy complex.

D-30 of all modifications were produced serially at the Perm Engine Plant (now JSC UEC-PM). There were about 3000 D-30 engines manufactured in total including all its series.
